Coral Reefs, the Human View
Part B: A Closer Look at Coral
Corals live in the sea, but sometimes we find pieces of them on land. Perhaps you've stumbled across a fragment of coral on a beach or have seen a piece of coral jewelry. Although you should never remove coral from the ocean or buy precious coral jewelry, studying the skeletal remains of coral can help us learn about what they were like when they were still alive.
- Examine the coral samples brought in by your teacher, first by eye and then with a magnifying glass or under a microscope if possible. For each sample, consider the following questions:
- Where did the coral sample come from?
- Is the surface of coral sample rough or smooth to the touch?
- Is the coral sample white or colorful?
- What shape is the coral sample? Is it symmetric?
- Do the coral samples brought into class look like the corals you saw in the videos? What makes them similar or different?
- Coral reefs are teeming with life on every surface, in every crevice, and in the surrounding waters. Examine a living coral reef ecosystem by visiting a local aquarium or by checking out the following web cams with live streaming video:
